How to run FreeBSD ARM64 and RISC-V64 images under FreeBSD x86_64

Quick and easy way to try out FreeBSD Arm64 and RISC-V64 images on a x86_64 host.

Notes:

• We are going to use the pre-built VM images supplied by FreeBSD instead of installing from scratch.
• We will convert the .raw image files to zvols
• We will bridge the network interface on the host and use a tap interface on the VM

Step 1: Install Necessary Packages

Pythonic way to setup Python Development Environment on FreeBSD

This gist lists steps needed to setup python development environment on FreeBSD using isolated virtual environments.

Why not use pkg or ports?

• Pythonic way is to create virtual enviroments for projects and add libs to these venvs not system python.
• Binary packages available only for one python version. Currently this is 3.8.
• Although we can build python packages against another version using ports, it's still not the Pythonic way.
